New description: [New technical field] _ This is a new type of (4) that is to set up the front foot of the nail at the front of the nail, so that the foot unit can be flipped after being seated and positioned. The footrests provided on the rafts are pushed outwards and pushed out, so that the legs of the county seaters can be stretched comfortably and supported by the footrest unit. [Prior Art] - (4) Gongshang County can sit back and back, and the armrests • Yes, the arms are not supported by the 'occupant's legs, but they don't have the possibility of thinking about their comfort needs'. Massage chairs, rest or sofa chairs, but this device has long been available, so in order to have the same foot function on the office chair, it is like the announcement of the M399663 "seat seat folding frame" The new type of patent (the same case also has a utility model patent in the mainland, the case number is CN201020544789), its main structure includes: two rotating arms and a bearing surface hinged between the two rotating arms, two The root swivel arm is articulated with the chair seat plate and the silk provided in the paving can comfortably spread the money on the carrying surface. It promotes blood circulation and relieves fatigue of the feet. It can be applied to all heights, legs and legs. Long people use. However, since the two rotating arms can only be turned upside down and then the bearing is turned outwards and extended, the occupant's foot can be placed. If the occupant only wants to stretch slightly downward, it will This function is not provided; in addition, since the bearing surface is spliced at the end of the two rotating arms, and the width of the two rotating arms is almost the same as the width of the seat, when the occupant uses the bearing surface, the two feet must Open the 'opening' to allow the two rotating arms to flip up, and the bearing surface must be turned outwards before use. Although it is not difficult to carry the externally facing operation M429423, but the opposite is to reverse the bearing.

Therefore, by the above-mentioned new type of footrest device locked at the front end of the office chair cushion, the footrest frame can be folded under the seat cushion or extended in front of the seat cushion by the pivotal positioning of the arm of the branch arm. The occupant's legs are raised and stretched to carry out 'the launching or retracting of the foot frame' is not only easy for the occupant to operate. It can even be completed by pushing or returning the hook, so that the operability of the footrest device is more in line with the needs of the actual application. Therefore, the present invention can be fully understood by the following embodiments and with reference to the accompanying drawings, and is implemented according to the following: [Embodiment] f See the -®, the new footrest device s is installed at the office The seat of the chair = the lower part of the rafter', which mainly includes an adjustable positioning seat that can be locked on the seat, and the unit 1 is pivoted, and a support arm 2 can be pivoted on the adjustment positioning unit 1 Then, let the arm 2 be worn by the person-supporting foot frame 3 with the supporting surface, and please refer to the second, third, and fourth figures, wherein the adjustment is set, and the single tl 1 X is set. The utility model comprises a fixing seat 1Q which can be coupled to the seat cushion, and a left and right pivoting seat Ua, 11b respectively coupled to the two sides of the fixing seat 0, and a pivoting portion 20 provided at the upper end of the supporting arm 2 , that is, pivoted between the two pivot seats 11a to Ub, and at the inner end of the right side of the plum-fit seat lib, the convex portion 11G having the limit groove ηι of the pre-turn angle range is provided. The end portion of the pivot portion 2G of the corresponding branch arm 2 is provided with a recess 24 for receiving the convex portion 110, and a convex portion 24 is protruded at the 5 recessed portion 24. The abutting 23' extending into the limiting groove 111 can thereby make the angle of the swinging of the supporting arm 2 to be within a predetermined range; in addition, a screw 17 is further disposed through the pivoting seat lib and the pivoting portion. After 20, the M429423 is sequentially inserted through the spring 12 and a ratchet seat 13, and then passed through the other rocking seat 11a to be locked and coupled with a nut 14, and one end of the ratchet seat 13 is set. The polygonal anti-rotation portion m is engaged with the polygonal concave portion 21 provided at the corresponding portion of the frame solid portion 2〇, and the spring 12 is also accommodated in the concave portion 21 and the ratchet seat 13 is provided. Producing an outward elastic pushing action, and further providing the other end of the ratchet seat with a ratchet 132 so that it can be corresponding to the corresponding ratchet portion provided in the recess on the left side drag seat 11a of the opposite portion 113 is engaged with each other; secondly, the outer end of the pivoting seat 11a is provided with a button 15, and the upper ring φ 5 of the button 15 has a plurality of legs 151' so that the legs 151 can pass through the pivoting seat 11a. Each of the through holes 112 is provided to be fastened and the end of each of the top legs 151 is abutted on the end surface of the ratchet seat 13, and then the button is again A spring 16 is disposed between the pivoting base 15 and the pivoting seat lu, so that the spring 16 can elastically push the button 15 outwardly, that is, when the button 15 is pressed, the thrust of the ratchet seat 13 is transmitted through the top leg 151. The action causes the ratchet portion 132 of the ratchet seat 13 to retreat from the engagement with the ratchet portion 113 of the pivoting seat 11a, that is, the support arm 2 can be flipped; and vice versa when the pressing force of the button 15 is released. Thereafter, the ratchet seat 13 and the button 15 are caused by the fact that φ is the spring force of the spring 12 and the elastic force of the magazine 16 and the button 15 is retracted to the home position. The ratchet portions 132, 113 are again in a state of being kept sprayed, that is, the support arm 2 is positioned after being turned over to a predetermined angle. In addition, as shown in the fifth figure, the inner side of the support arm 2 is recessed with a plurality of positioning recesses 22 ′ and the support arm 2 can be inserted into the sliding track 31 provided on the foot frame 3 , and A back cover seat 32, which is a part of the sliding tunnel 31, is fixed at the notch of the upper end of the sliding path 31, and then a position of the spring 34 is pushed between the back cover 32 and the support arm 2. The element 33 is engaged with the positioning element 33 by being elastically engaged into the corresponding recess 22, so that the foot frame 3 can be slid back and then passed through the recess at both ends of the arm 2. 'Let the foot frame 3 be positioned in the swaying or retreating. As shown in the sixth figure, 'When the pedicure device s is not used, it is turned down and folded under the seat cushion. When it is intended to be used, it is not as shown in the seventh figure except for the support arm 2 After the upward flipping position, the foot frame 3 is flipped from the bottom of the seat to the front of the seat cushion, and then the foot frame 3 is pushed outwardly along the support arm 2 to be positioned, and the foot frame is positioned 3 In the position that meets the extension of the occupant's leg; therefore, the operation of the entire pedestal device S is not only simple and easy, but also the extension of the support frame 3 or the retraction of the pedestal 3 can be used to resist the foot of the seater of the county. Easy to reach, making the rider's operation easier and easier. The above-mentioned embodiments have disclosed and described the present invention in a more specific manner, which can be clearly understood by those skilled in the art, and the various changes in the various types and methods of the present invention should be It does not deviate from the spirit and scope of this new type.
